' UNITE STATES PATENT OFFICE.

Application filed 'rebmry To. all whom it may concern:

Be it known that I, Hnnnn'r R. CRANE, a citizen of the United States, residmgat Los Angeles, in the county of Los Angeles and State of California, have invented new and useful Improvements in Flush-Valve-Bulb Guides, of which the following is a speclfication.

This invention relates to valve guldes and it has special application to valves employed in-flush tanks.

One object of my invention is the provision of means for properly positioning a valve on its seat.

Another object of my invention is the provision of a detachable guide for a valve.

.A further object of my invention 1s the provision of a guide which may readily be attached to and detached from a flush valve bulb.

With the foregoing objects in view, together with such other objects and advantages as may subsequently appear, my invention consists in the constructlon and arrangement of parts hereinafter described and claimed and illustrated in the accompanying drawings, in which Figure 1 is an elevational V16W.Of a flush tank partly in section, showing a discharge pipe in section and a valve to which is attached my improved means for guiding the valve, the valve being shown in closed pos1- tion.

Fig. 2 is an elevational view of a flush tank partly broken away and partly 1n section, showmg connection to a discharge pipe and a valve raised from its seat.

Fig. 3 is a central longitudinal section of a flush valve bulb and a gude of my invention, and

F1g. 4 is a plan view of Flg. 3.

Referring to the drawings or a more detailed description thereof, the numeral 7 indicates. a flush tank having a bottom 8, provided with an aperture 9 thru which passes a threaded nipple 10.

A ipe 14: has an outwardly extending upper ange 15 which abuts against a plate 12 having a central aperture, the plate 12 being held against the lower end of the nipple 10. The pipe 14 is secured to the plate 12 by a coupllng 17 which threadedly engages'the nipile 10 and which is recessed to support the ange 15 of the ipe 14.

Encircling the aperture 9 in t e bottom 8 of the tank 7 and resting on the upper face to its proper 18, 1824. Serial Ho. 898,763.

of the bottom 8 is a valve seat 18 adapted to receive a valve 20. The valve 20, as shown in Fig. 3, is a hollow circular bod the lower periphery of which is outwardly convex. The valve 20 is preferably made of rubber and comprises a boss 21, in the up er portion of which is inset a metallic y 22 having a threaded aperture 22 in axial alignment with the bulb 20 and is adapted to threadedly engage avertical rod or stem 23, as shown in Figs. 1 and 2.

The bottom ortion of the valve bulb 20 is provided wit an aperture 25 adapted to receive a valve guide 27' constructed in accordance with my invention. The guide 27 comprises an elongated hollow circular body provided with a longitudinal aperture 28 extending therethru and having the lower portion of its periphery tapered. The guide 27 is'provided at its upper end with a circular flange 29 which is held against the portion of the inner surface of the valve 20 surroundin d h m h d ing means or etac a y securin t e i e 27 to the valve 20. a gu In the operation of previous flush tank valves considerable annoyance has been experienced by an improper seating of the valve, resulting from its displacement from the true position.

In the operation of my device, however, during the closing action of the valve the guide 27 will engage the aperture in the transverse plate 12 and pass therethru, thus functionin to properly seat the valve 20.

It will understood that the guide 27 will not fail to engage the aperture in the the aperture 25, thus furnishplacement'of the valve 20 which may occur is not sufiicient to throw the axisof the uide outside the (peripheigeof the aperture in the plate 12, an it will seen that when the lower end of the guide 27 is within the aperture in the plate 12 it will be brought osition in the aperture even though its axis may not coincide with the axis of the plate aperture when it first enters the latter. The axial coincidence of the rture in the plate 12 and the guide 27 will ect a proper seating of the valve 20, inasmuch as t e latter is axially aligned with the guide 27 as well as with the seat 18 and the aperture in the plate 12.

It will be seen that accordi to my in vention either the valve 20 or t e ide. 27 may be replaced with a correspon mg new Pfili) when worn out and if the flange 29 of t e ulled or ushed through the aperture in the bottom 0 the valve 20.

While I have herein described one form of m invention modifications thereof may be evised without departin from the spirit thereof, and it is to be an erstood that such modifications come within the scope of this invention.

I claim as my invention:

1. A flush valve bulb guide comprislng an elongated tapered rubber member provided with a flange adapting it to be attached to a flush valve bulb.

2. A flush valve bulb guide, com rising an elongated tapered rubber member iaving a longitudinal aperture therethru and provided with a flange adapting it to be attached to a flush valve bulb.

3. In combination, a hollow flush valve bulb having an aperture thru its bottom and an elongated tapered flanged guidepassing thru said aperture and de ending from said bulb being held thereto y the contact of its flange with the inner face of said bulb.

4. In combination, a hollow rubber flush valve bulb having an aperture through its bottom and an elongated ta ered flanged rubber guide passing thru sai aperture and y the contact of its flange with the inner face of said bulb. r

5. In combination, a hollow flush valve rubber bulb having an aperture thru its bottom and an. elongated tapered flanged rubber guide passing thru said aperture and depending from said bulb, being held thereto by the contact of its flan e with the inner face of said bulb, said gui e having a longitudinal aperture therethru.

(i. The combination of a tank, a discharge tube leading from said tank, a plate positioned transversely in said tube and having a transverse aperture, a valve seat, a valve, a detachable elongated tapered uide depending from said valve and positioned to passreciprocally through the aperture of said plate.

7. The combination of a tank, a discharge tube leading from said tank, a plate posi tioned transversely in said tube and having a transverse aperture, a valve seat, a hollow rubber valve, a detachable elongated tapered hollow rubber guide depending from said valve and positioned to pass reciprocally through the aperture of said plate.

In testimony whereof I have signed my name to this specification.
